Nowadays, parking problem in urban cities has getting more and more urgent. Most of the problems are mainly due to the information share and management. In the work, we develop a cloud platform based on Huawei soft Ker cloud. On the cloud platform, we build a new smart parking platform, and implement methods, programs, and simulation test system for design and debugging. The functions of license plate recognition, car search and navigation, payment, parking lot search, intelligent parking are implemented in the platform through code debugging.
